ELECTRIC SAD-IRON.

Specification of Letters Patent.

Patented June 111, 1912.,

To all whom it may concern:

Be it known that I, Vi'KToR SoHILn, a citizen of the Confederation of Switzerland, residing in Brienz, Switzerland, have invented certain new and useful Improvements in Electric Sad-Irons, of which the following is a specification.

This invention relates to an improved electric sad-iron, in which a comparatively thin bottom-plate and a thick and heavy cover-plate are used so as to permitthe transmission of a greater quantity of heat to the bottom-plate and of a lesser quantity to the cover-plate.

Heretofore electric sad-irons were 7 made in which the cover-plate rested directly on a comparatively thick and heavy bottom-' plate. These irons were objectionable, as too little heat was transmitted through the bottom-plate and too much heat transmitted to the cover-plate owing to the large contact surface between the same. In electric sad-irons made in one piece, too greata quantity of heat was likewise transmitted to the upper or covering portions of the same. The use of these sad-irons was comparatively expensive owing to the great heat transmission to the covering portion and the too small heat transmission to the bottomplate.

The object of this invention is to furnish an electric sad-iron by which the defects referred to are, obviated, and the'invention consists of an electric sad-iron comprising a flanged bottom-plate, a cover-plate, and a heating-element supported on the bottomplate, the bottom-plate being provided with raised center and corner-portions for the heating-element. The cover-plate rests by its thin lower edge on the recessed flange of the bottom-plate tact-surface with the bottom plate, -which heating-element is supported in such a manner that it does not come in contact with the cover-plate.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved electric sad-iron; Fig. 2 is a top-view of the bottom-plate, and Fig. 3, a vertical transverse section.

Similar letters of reference indicate corresponding parts in the difi'erent figures of the drawings.

so as to form a small con.

bottom plate out Referring to the drawings, or represents the bottom-plate and o the conveXo-concave top or cover-plate of my electric sadiron. The covering-plate 0 forms with the bottomplate a an entirely closed body for receiving a heating-element d of any approved construction. The bottom-plate a is provided with a raised flange a along its entire outer edge, as shown in Figs. 2 and 3, said flange being provided with a small recess a which forms a seat for the lower tapering edge 0' of the cover-plate 0. The heating-element (Z is firmly held in position on the bot-tomplate a and supported on and between raised central and corner-bosses e, c in such a manner that neither the heating-element nor its asbestos coveringplate forms contact with the cover-plate, and its contact termi nals d may rest on the intermediate lugs e".

The bottom-plate a is made comparatively thin, while the cover-plate is made thick and heavy so that the greatest possible quantity of heat is transmitted through the thin bottomplate and the least possible quantity of heat to the cover-plate, owing to the small contact-surface between the two plates. The cover-plate is attached by fastoning-screws f, f at the front and rear end to the bottom-plate a.

The improved electric sad-iron furnishes greatly increased heat-transmitting elfects and a saving in current as compared with the sad-iron heretofore used.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

An electric sad 'iron comprising 'a bottom plate having a recessed flange on its upper edge, an arched cover plate having a dependent lip on itsunder side engaging said recessed flange, aheater disposed in said of contact with said cover plate, and means for securing said plates together,

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
